# ISO 13567

ISO 13567 is an international computer-aided design (CAD) layer standard.

## Standard parts

The standard is divided into three parts:

### ISO 13567-1:2017

    Technical product documentation — Organization and naming of layers for CAD — Part 1: Overview and principles

### ISO 13567-2:2017

    Technical product documentation — Organization and naming of layers for CAD — Part 2: Concepts, format and codes used in construction documentation

### ISO/TR 13567-3:1999 (withdrawn September 2015)

    Technical product documentation — Organization and naming of layers for CAD — Part 3: Application of ISO 13567-1 and ISO 13567-2
Standard has been developed by Technical Committee TC 10 (Technical product documentation) Subcommittee SC 8 (Construction documentation); Refer. ICS: 01.110; 35.240.10.

## Structure of layer names

CAD layer names are structured as a series of mandatory and optional fixed length fields, composed as a continuous alpha-numerical text string.

### Mandatory fields
#### Agent responsible (clause 6.1)

(2 characters, indicating the person or organisation responsible for the layer information—manufacturer,

#### Element (clause 6.2)

(6 characters, indicating the functional parts of construction works or structure): follows a classification system like CI/SfB building codes or Uniclass codes;

#### Presentation (clause 6.3)

(2 characters, related to the information graphical presentation)

### Optional fields
#### Status (clause 7.1)

(1 character, status of the physical part, ISO code)

#### Sector (clause 7.2)

(4 characters, physical subdivision of construction work, recommended to use ISO 4157-2/3 codes)

#### Phase (clause 7.3)

(1 character, time or logical subdivision of work)

#### Projection (clause 7.4)

(1 character, work multiple views differentiation, ISO code)

#### Scale (clause 7.5)

(1 character, classification of layer information by the scale of final drawing, ISO code)

#### Work Package (clause 7.6)

(2 characters, materials and/or work sections)

#### User Defined (clause 7.7)

(unlimited, additional subdivision or help plain description): description or subdivision.

### Special characters
## Applications
### Resulting length

In practice, application of ISO 13567 fields can lead to short names (only mandatory fields), or much longer names (use of some or all optional fields in complex projects).

### Short name samples
#### A-B374—T-

    agent Architect, element Roof window in SfB, presentation text

#### A-B374—E-

    agent Architect, element Roof window in SfB, presentation graphic element

#### Other

* A-374---T-
* A-24—__D-

### Long name samples
#### A-37420-T2N01B113B23pro

    agent Architect, element Roof Window in SfB, presentation Text#2, New part, floor 01, block B1, *phase 1, projection 3D, scale 1:5(B), work package 23 and user definition "pro"

#### A-G25---D-R

    agent Architect, element wall in Uniclass, presentation dimensions, status Existing to be removed

#### Other

### List of layers in a standard architectural drawing

Agent is Architect, using ISO 13567 and Uniclass or CI/SfB Classification System.

#### Architectural layers using Uniclass

Uniclass 1.4 now superseded by Uniclass 2015
Using Uniclass Table G and Table H (exceptionally F and J tables).
Note: Elements cut by section has been provisionally indicated as A-****--E5 (reflecting the use of a wider line). An alternative -but longest- notation could be A-****--E-------2 (defining the view as section) or A-****--ES.
